Ecological Engineering Measures for the Control of Nutrient Transport from Watersheds

The most typical ecological engineering measures for the controlling of nutrient transport from watersheds are erosion control on upland areas and slopes (strip cropping, no tillage treatment, terracing, hedgerows, and shelterbelts), free water surface (FWS) CWs for the treatment of polluted water from agricultural catchments, and riparian buffer zones and buffer strips that have multiple ecological functions (Figure 4).

The following sections will concentrate on riparian buffer zones and buffer strips as well as CWs used in the control of nutrient fluxes in watersheds.
